After the MacBook AIr enters the dormant state and wakes up from the dormant state, the mouse icon has been rotating and cannot log in to the system. A crash occurs. After forcibly pressing the power button, restart the system to log in. This problem often occurs in macOS Catalina 10.15.2 and above. The reason for this problem is caused by the BUG of the input method that comes with the OS system. After the input method that comes with the OS is disabled, the problem is solved after the author's own computer test, and there is no subsequent crash after sleep wakeup. Users who have this problem can solve it by the following methods:
1. Click the apple icon in the picture and select "System Preferences".
2. Select " Keyboard ".
3. Click the "input method" option, and delete the system default input methods "Simplified Pinyin", "Simplified Handwriting", "Simplified Strokes" and "Simplified Shuangpin". (After deleting, there may be no input method available in the system, please install other third-party input methods, such as Sogou Pinyin or Wubi before deleting).
